SWITCH FOR B BATTERIES.

Application filed April 15, 1924. Serial No. 706,681.

The present invention relates to switches for variable voltage batteries and conslsts in the combinations and arrangements of elements hereinafter described and particularly set forth in the accompanying claim.

With the use of the so called B-batteries in radio selective voltages are now obtained only by manually connecting the terminal wire with that binding post of the battery having the voltage desired, and this manipulation has the disadvantages of requiring both hands of the operator, prolonged interruption and distraction. It is to overcome these faults that the device disclosed herein is proposed.

The invention therefore has for its purpose to provide a switch, as an article of manufacture, adapted to any type of B-battery used in radio wherein the different volta 'es ma 1 be selected in a nick eas and a a a convenient manner and by a simple manipulation of the hand.

A further purpose of the invention is to provide a self contained switch of this character to the end that the same may be manufactured and sold as a singleunit and adapted for ready attachment to any type of B- battery without in any way altering said battery or necessitating the use of separate attaching devices.

The present invention is shown by way of illustration in the accompanying drawings wherein: s

Figure 1 is a top plan view of the switch;

Figure 2 a sectional view thereof;

Figure 3 a detailed view of the contact maker; and

Figure 4i a detailed view of the contact maker actuating handle.

Referring to the construction in further detail, 5, designated a base piece or support of suitable insulating material, on which is mounted and radially arranged a plurality of connectors 6, preferably formed from spring terminal clips of the Fahnestock type having the usual wire engaging portions 7, conveniently placed to receive and grip the wires by a simple and easily performed operation. The shank portions of the several clips are secured to the base piece 5 by hollow rivets 8 whose up-set portions 9 provide suitable points for the contact maker or arm 10 that is pivotally mounted on the pin 11 and actuated by the knob or turning handle 12' as .shown. The contacting portion has a depression 13 to produce the necessary stopping or holding quality when the contact maker is engaged.

It will be understood, of course, that the several terminal clips 6 are connected with their respective voltage batteries.

A terminal clip 14 of the same type as clip 6 has its shank portion 15 engaging the pin 11 for establishing a circuit through the contact maker 10 and the particular clip 6 connecting with the battery having the selected voltage.

It is to be understood that I do not desire to limit myself to the precise details of construction and arrangement herein set forth, as it is obvious that various modifications may be made therein without departing from the essential features of the invention.

What is claimed as new is:

In a switch for multiple voltage batteries, the combination with a plurality of uniform commercial clips; of a base having substantially sectoral shape with smooth top and bottom surfaces and being made of insulating material, a contact arm having a suitable handle and a projecting contact point, one of said clips forming a terminal for a conductor, a pivot member for the contact arm and said terminal clip situated adjacent the apex of said base, tubular contact members adapted to carry the other of said clips in arcuate formatlon around said pivot mem-.

ber, securing means for said pivot and contact members, respectively, counter-bores being provided on the underside of said base for concealingly housing said securing means in the body of the base, said contact point being adapted to selectively engage saidtubular contact members, all of said clips being arranged on the top surface of the base and no parts projecting from the bottom surface thereof, substantially as set forth.

In testimony whereof we afiiz: our signatures.
